Frequently Asked Questions
What is the peel force range of YJLG-80/81, and why does it matter?
The YJLG-80/81 tape has a peel adhesion force of 30–70 grams. This low-tack range is carefully controlled to ensure reliable bonding during the encapsulation process while allowing clean, residue-free removal afterward—critical for maintaining surface cleanliness on precision electronic components.
Will YJLG-80/81 leave adhesive residue after removal?
No. YJLG-80/81 is specifically engineered for clean peeling. When removed correctly, it leaves no adhesive residue on the component surface, making it ideal for applications where surface cleanliness is a strict requirement, such as LED and FPC encapsulation.
What anti-static options are available for YJLG-80/81?
YJLG-80/81 offers three anti-static grade options: single-sided brown (10⁵–10⁸ Ω), single-sided light blue (10⁶–10¹⁰ Ω), and double-sided anti-static (10⁶–10¹¹ Ω). Users can select the appropriate grade based on the electrostatic sensitivity level of their components.
Can YJLG-80/81 withstand high-speed automated mounting processes?
Yes. With a tensile strength of ≥2.5 kg and elongation of ≥30%, YJLG-80/81 is built to resist breakage and deformation under the mechanical stress of high-speed mounting and transportation operations, ensuring consistent performance on automated production lines.
What standard widths are available, and can custom sizes be ordered?
The standard width range covers 5.4 mm to 97.5 mm, accommodating a wide variety of component sizes. Custom widths and specifications are fully supported, allowing manufacturers to obtain tape dimensions precisely matched to their production requirements.
What is the thickness tolerance of YJLG-80/81, and why is it important?
YJLG-80/81 maintains a uniform thickness of 0.06 mm with a tight tolerance of ±0.005 mm. This precise thickness control is essential for maintaining consistent tape performance across rolls, ensuring reliable encapsulation results and compatibility with automated equipment that requires dimensional stability.
